Spire.Doc for Java 是一款专业的Java Word组件，开发人员使用它可以轻松地将Word文档创建、读取、编辑、转换和打印等功能集成到自己的Java应用程序中。

Spire.Doc for Java支持将外部文件（Word，Excel，PowerPoint，PDF，图片，视频等）作为OLE对象嵌入到Word文档中。本文为您提供了一个如何将PDF文件插入Word文档的示例。可点击此处下载最新版测试。

示例代码如下：

import com.spire.doc.Document;
import com.spire.doc.FileFormat;
import com.spire.doc.Section;
import com.spire.doc.documents.OleObjectType;
import com.spire.doc.documents.Paragraph;
import com.spire.doc.fields.DocOleObject;
import com.spire.doc.fields.DocPicture;

public class InsertOLE {

    public static void main(String[] args) {

        //Create a Document object and load a Word document
        Document doc = new Document();
        doc.loadFromFile("C:\\Users\\Administrator\\Desktop\\source.docx");

        //Get the last section
        Section section = doc.getLastSection();

        //Add a paragraph
        Paragraph par = section.addParagraph();

        //Load an image which will be inserted to Word document representing the embedded file
        DocPicture pdfIcon = new DocPicture(doc);
        pdfIcon.loadImage("C:\\Users\\Administrator\\Desktop\\pdf-icon.jpg");

        //Insert a PDF file to the Word document as an OLE object
        par.appendOleObject("C:\\Users\\Administrator\\Desktop\\report.pdf", pdfIcon, OleObjectType.Adobe_Acrobat_Document);

        //Save to another file
        doc.saveToFile("EmbedDocument.docx", FileFormat.Docx_2013);
    }
}
